Abstract

In order to make the grout spreading in coal and rock fractured network more direct-viewing, the parallel plate model is used to analyze grout flowing in a fracture primarily, then the grouting pressure drawdown formula in a single fracture is established. At the same time, the influence of the fracture aperture and the inlet grouting flow volume rate in unit width of fracture on the width of the plug term is analyzed too, and the stress intensity factor is quoted to analyze the fracture propagation orientation and propagation length at the state of compressive-shear and tensile-shear conditions. Based on this, grout flowing simulation in intermittent fractured network is done by FORTRAN language programming, which can guide the construction of grouting projects effectively.
